Embodiment 1

[0046] See figure 1 .

[0047] The plug-flow combined bioreactor exhaust gas treatment equipment made of plastic plates has a length, width and height of 70cm, 50cm and 1000cm respectively, and a total volume of 0.35m 3 , including a plug-flow combined bioreactor 21 with packing, circulation pumps 8 and 13, etc.

[0048] The exhaust gas enters the lower area 5 of the partition plate 6 with holes from the bottom air inlet 3 of the upward flow bioreactor 1, and the water-soluble substances in the exhaust gas are absorbed and degraded by the microorganisms in the water; at the same time, the gas is pre-wetted . The undegraded hydrophobic pollutants flow upwards, pass through the partition plate 6 with holes and enter the upper area 7 filled with fillers 9, and are degraded by fungal microorganisms attached to the fillers 9. The remaining undegraded pollutants enter the downward-flowing biological reaction zone 19 from the top of the upward-flowing biological reaction zone 1 a...

Abstract

This invention relates to a waste gas treatment device through bioreactor, which belongs to the environment protection field. The device comprises two biological reaction areas: upward flow area and downward flow area, wherein between the two areas is arranged the segregation barriers whose upper is connected. Inside both reaction areas are set the perforated baffle, and the lower of the baffle is float the microbe, the upper is filled with stuffing, and the microbe attached grows in the stuffing. Two side-walls of the reactor are set fountain inlets, and the two inlets are connected through the perforated pipe. The invention uses the cooperating action of the fungus and bacteria to remove the hydrophilicity and hydrophobicity contaminant at the same time; in addition, the upward flow and the downward flow are associated to form the propelling bioreactor, which can prolong the stay of the waste gas in the reactor.

Description

technical field [0001] The invention belongs to equipment for treating waste gas by using a bioreactor, in particular to a plug-flow combined bioreactor waste gas treatment equipment. Background technique [0002] At present, a lot of research and development and engineering practice have been carried out for the treatment of conventional pollutants such as industrial wastewater, urban domestic sewage, atmospheric smoke, sulfur dioxide, nitrogen oxides, and solid waste, and good progress has been made. Odor substances and volatile organic compounds will be produced during the generation, discharge or treatment of the above pollutants. Although the concentration is low, it will produce strong sensory stimulation. Some odors and volatile organic waste gases are toxic and seriously endanger human health and the ecological environment. The harm to human beings caused by the malodorous substances that escape into the air has become one of the seven major environmental hazards in...
